FEATURES - T6 SERIES MOBILE APPLICATION GREATER FLOW HIGHER PRESSURE BETTER EFFICIENCY MOUNTING FLEXIBILITY LOWER NOISE LEVELS COMPLETE CONFORMITY CARTRIDGE DESIGN WIDER RANGE OF ACCEPTABLE VISCOSITIES FIRE RESISTANT FLUIDS Greater flow for the envelope size is achieved by increased displacement cam rings : at high permissible speeds with atmospheric inlet C 3 to 31 GPM,.66 to 6.10 in 3 /rev. D 14 to 50 GPM, 2.90 to 9.64 in 3 /rev. E 42 to 72 GPM, 8.07 to 13.86 in 3 /rev. Pressure ratings to 4000 PSI reduce size and cost of actuators, valves and lines, give extended life at reduced pressures. Better efficiency under load increases productivity, reduces heating and operating costs. Up to 32 positions for double pumps and up to 128 for triple pumps: this reduces mounting costs and improves performance. Increase operator safety and acceptance. To SAE - J744c 2-bolt standards and to ISO 3019-1 (T6EDCS SAE E, T6EDCM ISO 3019/2) in the various keyed and splined shaft options offered. Provides for drop-in assemblies. This allows easy conversion or renewal of serviceable elements in minutes at minimum expense and risk of contamination. The "C" & "D" cartridge pumps are birotational and indicated by "B" description in cartridge model number. Pump rotation is easy to change by changing position of cam ring on port plate dowel pin hole. Viscosities from 9240 to 60 SUS permit colder starts and hotter running. The balanced design compensates for wear and temperature changes. At high viscosity or cold temperature, the rotor to side plates gap is well lubricated and improves mechanical efficiency. Including phosphate esters, chlorinated hydrocarbons, water glycols and invert emulsions may be pumped at higher pressures and with longer service life by these pumps. GENERAL APPLICATIONS INSTRUCTIONS 1. Check speed range, pressure, temperature, fluid quality, viscosity and pump rotation. 2. Check inlet conditions of the pump, if it can accept application requirement. 3. Type of shaft : if it would support operating torque. 4. Coupling must be chosen to minimize pump shaft load (weight, misalignment). 5. Filtration : must be adequate for lowest contamination level. 6. Environment of pump : to avoid noise reflection, pollution and shocks. 3

PRIMING AT STARTING At first, start operation of the pump shaft at the lowest speed and at the lowest pressure to obtain priming. When a pressure relief valve is used at the outlet, it should be backed off to minimize return pressure. When possible, an air bleed off should be provided in the circuit to facilitate purging of system air. Never operate pump shaft at top speed and pressure without checking for completion of pump priming, and the fluid has no aeration disaerated. 4

First calculation Vi = 231 Q n 2. Choice Vi of pump immediately greater (see tabulation) 3. Theoretical flow of this pump q Vi = Vp x n 231 4. Find q Vs leakage function of pressure q Vs = f(p) on curve at 60 or 115 SUS Vi = 231 x 15.8 1500 = 2.43 in 3 /rev. T6CM B14 Vi = 2.81 in 3 /rev. q VI = 2.81 x 1500 231 = 18.2 GPM T6CM (page 10) : q VS = 1.3 GPM at 2200 PSI, 115 SUS 5. Available flow q Ve = q Vi - q Vs q Ve = 18.2-1.3 = 16.9 GPM 6. Theoretical input power Pi = qvi x p 1714 7. Find ps hydrodynamic power loss on curve 8. Calculation of necessary input power P = Pi + Ps Pi = 18.2 x 2200 1714 = 23.4 HP T6CM (page10) : Ps at 1500 R.P.M., 2200 PSI = 2.1 HP P = 23.4 + 2.1 = 25.5 HP 9. Results Vi = 2.81 in 3 /rev q Ve = 16.96 GPM P = 25,50 HP T6CM B14 These calculation steps must be followed for each application. INTERMITTENT PRESSURE RATING T6 units may be operated intermittently at pressures higher than the recommended continuous rating when the time weighted average of pressure is less than or equal to the continuous duty pressure rating. This intermittent pressure rating calculation is only valid if other parameters; speed, fluid, viscosity and contamination level are respected. For total cycle time higher than 15 minutes, please consult your DENISON Hydraulics representative. Example : T6CM - B14 Duty cycle 4 min. at 4000 PSI 1 min. at 500 PSI 5 min. at 2300 PSI (4 x 4000) + (1 x 500) + (5 x 2300) 10 = 2800 PSI 2800 PSI is lower than 3500 PSI allowed as continuous pressure for T6CM - B14 with HF-0 fluid. 6

DESCRIPTION - T6 SERIES MOBILE APPLICATION Cap end outlet port has 8-positions at 45 intervals relative to inlet on T6DC. Inlet Shaft end outlet port has 4-positions at 90 intervals relative to inlet. Front & rear sideplates are each clamped axially by the separate discharge pressures. Outlet Inlet Pilot recess as required by SAE for full conformity. Shaft comes in variety of keyed and splined options to meet SAE and ISO 3019-1. Cartridges are replaceable assemblies. Each includes cam ring, rotor, vanes, pins and sideplates. Ball bearing hold shaft in alignment. T6*P double shaft seal Drain hole Front sideplate is clamped axially by discharge pressure to reduce internal leakage. Cartridge is replaceable assembly including cam ring, rotor, vanes, pins and sideplate Vane is urged outward at suction ramp by pin force and centrifugal force. 90 section Holes in cam ring improve wide cartridge inlet characteristics. Working vane on major arc pushes fluid to discharge port. Suction ramp where unloaded vane moves out. Section B-B Pin cavity is at a steady pressure slightly higher than at discharge port. Section A-A Lub side holes lubricate the sideplate surfaces. Discharge ramp where unloaded vane moves in. Working vane on minor arc seals discharge pressure from the suction port. APPLICATION ADVANTAGES The high pressure capability to 4000 PSI, in the small envelope, reduces installation costs and provides extended life at reduced pressure. The high volumetric efficiency, typically 94%, reduces heat generation, and allows speeds down to 400 RPM at full pressure. The high mechanical efficiency, typically 94%, reduces energy consumption. The wide speed range from 400 RPM to 2800 RPM, combined with large size cartridge displacements, will optimize operation for the lowest noise level in the smallest envelope. The low speed 400 RPM, low pressure, high viscosity 9240 SUS allow application in cold environments with minimum energy consumption and without seizure risk. The low ripple pressure=± 29 PSI reduces piping noise and increases life time of other components in the circuit. The high resistance to particle contamination because of the double lip vane increases pump life. The large variety of options (cam displacement, shaft, porting) allows customized installation. The shaft option T (SAE J718c), allows direct drive (at 540 or 1000 RPM) on tractors. The double shaft seal (T6*P version) and drain hole allow direct mounting onto gear boxes. 7

SHAFTS AND HYDRAULIC FLUIDS - T6 SERIES MOBILE APPLICATION RECOMMENDED FLUIDS ACCEPTABLE ALTERNATE FLUIDS Petroleum based antiwear R & O fluids. These fluids are the recommended fluids for T6 series pumps. Maximum catalog ratings and performance data are based on operation with these fluids. These fluids are covered by DENISON Hydraulics HF-0 and HF-2 specification. The use of fluids other than petroleum based antiwear R & O fluids, requires that the maximum ratings of the pumps will be reduced. In some cases the minimum replenishment pressures must be increased. Consult specific sections for more details. VISCOSITY Max (cold start, low speed & pressure) Max (full speed & pressure) Optimum (max. life) Min (full speed & pressure for HF-1, HF-3, HF-4 & HF-5 fluids) Min (full speed & pressure for HF-0 & HF-2 fluids) 9240 (SUS) 500 (SUS) 140 (SUS) 90 (SUS) 60 (SUS) VISCOSITY INDEX 90 min. higher values extend range of operating temperatures. Maximum fluid temperature (θ) F HF-0, HF-1, HF-2 + 212 HF-3, HF-4 + 122 HF-5 + 158 Biodegradable fluids (esters & rapeseed base) + 149 Minimum fluid temperature (θ) F HF-0, HF-1, HF-2, HF-5-0.4 HF-3, HF-4 + 50 Biodegradable fluids (esters & rapeseed base) - 4.4 FLUID CLEANLINESS OPERATING TEMPERATURES AND VISCOSITIES WATER CONTAMINATION IN THE FLUID The fluid must be cleaned before and during operation to maintain contamination level of NAS 1638 class 8 (or ISO 18/14) or better. Filters with 25 micron (or better ß10 100) nominal ratings may be adequate but do not guarantee the required cleanliness levels. Suction strainers must be of adequate size to provide minimum inlet pressure specified. 100 mesh (149 micron) is the finest mesh recommended. Use oversize strainers or omit them altogether on applications which require cold starts or use fire resistant fluids. Operating temperatures are a function of fluid viscosities, fluid type, and the pump. Fluid viscosity should be selected to provide optimum viscosity at normal operating temperatures. For cold starts the pumps should be operated at low speed and pressure until fluid warms up to an acceptable viscosity for full power operation. Maximum acceptable content of water. =0,10 % for mineral base fluids. 0,05 % for synthetic fluids, crankcase oils, biodegradable fluids. If amount of water is higher, then it should be drained off the circuit. COUPLINGS AND FEMALE SPLINES KEYED SHAFTS NOTE SHAFT LOADS = The mating female spline should be free to float and find its own center. If both members are rigidly supported, they must be aligned within.006 TIR or less to reduce fretting. The angular alignment of two spline axes must be less than ±.002" per 1" radius. = The coupling spline must be lubricated with a lithium molydisulfide grease or a similar lubricant. =The coupling must be hardened to a hardness between 27 and 45 R.C. = The female spline must be made to conform to the Class 1 fit as described in SAE-J498b (1971). This is described as a Flat Root Side Fit. DENISON Hydraulics supplies the T6 series keyed shaft pumps with high strength heat-treated keys. Therefore, when installing or replacing these pumps, the heat-treated keys must be used in order to insure maximum life in the application. If the key is replaced it must be a heat-treated key between 27 and 34 R.C. hardness. The corners of the keys must be chamfered from.030" to.040 at 45 to clear radii in the key way. Alignment of keyed shafts must be within tolerances given for splined shafts. These products are designed primarily for coaxial drives which do not impose axial or side loading on the shaft. Consult specific sections for more details. 8
